Photoshop CS6: Image always shifts one pixel after using transform tool

Here is another persistent annoyance I've found with the program. Whenever I alter an image using my transform tool, by either rotating, scaling or changing perspective, etc... when I hit return to set it in place, the image always moves slightly one pixel. Every time. I had an Adobe tech share my screen and they saw this happen to my images but had no answer for this anomaly and directed me here. This has been happening to me for years in multiple versions of Photoshop.

Have you installed all the updates for Photoshop CS6?
And does this happen in the current version of Photoshop (CC 2014)?

I have installed all the updates for CS6 but I haven't tried it with CC 2014. I know this has always happened for me with versions prior to CS6.

What view % is you document at when you see this happen?

With the project I'm currently working on, I selected part of a layer, selected transform, rotated it then moved it... and each time I did, at 66.67%, 100% and 200%, when I hit return, the section I was transforming moved one pixel from where I had stopped.

What I'm seeing is the transform (lower quality) preview do a final (high quality) render using the interpolation setting (so the whole object looks slightly different after I commit - which is expected). I need to experiment more with some other shaped objects to know if it's truly 'shifting' position.

It's frustrating, only happens with transform. I can select something, get the crawling ants around the image, move it and deselect and it's exactly where I positioned it before I deselected. Not so with transform.

In that case where you're only moving the high quality rendered pixels there's no intermediate transform preview to render.

Let me get this straight... so when I select something using either the lasso or marquee tools, they are high quality rendered pixels... but when I select something then apply transform, they are lower quality rendered pixels?

The transform uses a temp preview (using a lower quality interpolation method to make the transform fast). When you commit the transform, it gets rendered using the high-quality interpolation method you have selected in the transform tool options bar.
